A biased die is such that P(4) = 1/10 and other scores being equally likely.

Question:

A biased die is such that P(4) = 1/10 and other scores being equally likely. The die

is tossed twice. If X is the ‘number of fours seen’, find the variance of the

random variable X.

Solution:

Here, random variable X = 0, 1, 2

Therefore, the required variance = 0.18.
